Sony A7R IV vs RX1R
The Sony Alpha A7R IV and the Sony Cyber-shot DSC-RX1R are two enthusiast cameras that were officially introduced, respectively, in July 2019 and June 2013. The A7R IV is a mirrorless interchangeable lens camera, while the RX1R is a fixed lens compact. Both cameras are equipped with a full frame sensor. The A7R IV has a resolution of 60.2 megapixels, whereas the RX1R provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A7R IV and the Sony Cyber-shot DSC-RX1R? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
The physical size and weight of the Sony A7R IV and the Sony RX1R are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R is considerably smaller (41 percent) than the Sony A7R IV. It is worth mentioning in this context that the A7R IV is splash and dust resistant, while the RX1R does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R has a lens built in, whereas the A7R IV is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A7R IV and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the A7R IV gets 670 shots out of its Sony NP-FZ100 battery, while the RX1R can take 270 images on a single charge of its Sony NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX1R was launched at a lower price than the A7R IV, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the RX1R is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the Sony A7R IV offers a higher resolution of 60.2 megapixels, compared with 24 MP of the Sony RX1R. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 5.97μm for the RX1R). However, it should be noted that the A7R IV is much more recent (by 6 years) than the RX1R, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Sony A7R IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IV for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Sony RX1R are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The A7R IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the RX1R, the A7R IV has the capacity to capture high quality composite images (241MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Sony Alpha A7R IV has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
In terms of underlying technology, the A7R IV is build around a BSI-CMOS sensor, while the RX1R uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the A7R IV has a notably higher overall DXO score than the RX1R (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 1.2 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R IV provides a higher video resolution than the RX1R. It can shoot video footage at 4K/30p, while the RX1R is limited to 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R IV has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1R relies on live view and the rear LCD for framing. That said, the RX1R can be equipped with an optional viewfinder – the FDA-EV1MK.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A7R IV has a touchscreen, while the RX1R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7R IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sony A7R IV has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The A7R IV writes its imaging data to SDXC cards, while the RX1R uses SDXC or Memory Stick PRO Duo cards. The A7R IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX1R only has one slot. The A7R IV supports UHS-II cards (on both slots), while the RX1R cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Alpha A7R IV and Sony Cyber-shot DSC-RX1R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IV offers wifi support, while the RX1R does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Sony A7R IV (unlike the RX1R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the A7R IV and the RX1R have been discontinued, but can regularly be found used on ebay. The RX1R was replaced by the Sony RX1R II, while the A7R IV was followed by the Sony A7R V. Further information on the features and operation of the A7R IV and RX1R can be found, respectively, in the Sony A7R IV Manual (free pdf) or the online Sony RX1R Manual.
Review summary
So how do things add up? Is the Sony A7R IV better than the Sony RX1R or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Sony Alpha A7R IV:

Arguments in favor of the Sony Cyber-shot DSC-RX1R:
- Ready to shoot: Has an integrated lens, whereas the A7R IV necessitates an extra lens.
- More compact: Is smaller (113x65mm vs 129x96mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the A7R IV).
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in June 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the A7R IV is the clear winner of the match-up (28 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Sony A7R IV and the Sony RX1R place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A7R IV or the RX1R. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
